lived the kingdom's royal family. this is the acropolis, a magnificent group of palaces, temples, and plazas. 16 kings ruled here for almost 400 years. after his inauguration, each new king would build his own palace atop those of his ancestors. deep inside the acropolis these earlier buildings have now been discovered. here, a team of archaeologists has tunneled its way to an ancient tomb. so, you got it dug away, you think ? yeah. all right, well, let's do it. it's pretty complete. a little bit of it stayed behind there, but not too bad. boy, it's a big piece of jade.
